Fight Club had lackluster box office numbers and dismal reviews when it was released in 1999. Proving that critics and audiences don't always get it right, the movie has since been highly celebrated and is cemented as one of the best films of the 90s. For those who are unfamiliar, the film stars Brad Pitt and Edward Norton as a pair of nihilistic men who start an underground boxing ring, primarily made up of blue-collar, lower-class workers. Their underground fight clubs eventually escalate into a terrorist organization called Project Mayhem, which is made of men (also known as "Space Monkeys") from all over the country.

There are many memorable moments in Fight Club, but one of the most impactful was the surprising ending. Spoiler alert: the masculine and confident Tyler Durden and the awkward, bumbling narrator are actually the same person. Upon subsequent rewatches, it's easy to spot the clues that give away this big twist.
